This map shows how much it costs to transport oil across the US

In a recent note to clients, a Credit Suisse research team led by Jan Stuart shared a map showing the transport differentials for oil across the US.

The gray routes represent rail transport and the light-blue routes represent pipeline transport across the states. Meanwhile, the yellow, red, and dark teal represent transport by ship — with the color indicating the destination.

Notably, it's way more expensive to transport oil by rail than by pipeline.
